• ### When the graph of y = log (base 10) (2x) is drawn . why is 0.301 on y axis and 1 on the x axis marked. WHY?

WHEN THE GRPAH OF y = log (base 10) (2x) IS DRAWN we label the x int of 2 bcause it crosses that point. WHY ARE TH POINTS 0.301 on y axis and 1 on the x axis marked. WHAT IS THEIR SIGNIFICANCE?? DOES THIS HAVE ANYTHING TO DO WITH Domain & Range BECAUSE...

because when x=1 , y=log2 = 0.301
